Deck Balusters: Inside vs Outside

When it comes to home safety and aesthetics, deck balusters play a pivotal role. They not only provide support and stability to your deck but also contribute significantly to its overall appearance. One of the most common questions homeowners face is whether to place deck balusters on the inside or outside of the deck frame. Let's delve into this topic, exploring the pros and cons of each approach.

Before we dive into the details, it's essential to understand that the choice between inside and outside balusters often comes down to personal preference, local building codes, and the specific design of your deck. Always ensure your chosen installation method adheres to local safety regulations and building codes.

Inside Deck Balusters

Installing balusters on the inside of the deck frame, also known as between-the-joists installation, is a popular choice among homeowners. This method provides a clean, uniform look, as the balusters are hidden from view when standing on the deck.

One of the primary advantages of inside balusters is the enhanced safety they provide. With this installation method, there are no gaps between the balusters and the decking, reducing the risk of small children or pets getting trapped or objects falling through.

Installation Process

Installing balusters on the inside involves measuring and cutting the balusters to fit snugly between the joists. This process requires precision to ensure the balusters are level and evenly spaced. It's crucial to leave a slight gap between the balusters and the decking to allow for expansion and contraction due to temperature changes.

To secure the balusters, you'll typically use screws or nails, driving them through the baluster into the joist. Ensure you use appropriate fasteners and follow the manufacturer's guidelines for the best results.

Design Considerations

Inside balusters can create a sleek, modern look, especially when combined with matching handrails and newel posts. They work well with various baluster materials, including wood, metal, and composite.

However, it's essential to consider the visibility of the balusters from below. If your deck is elevated, you might want to choose a design that allows for some visibility, such as glass or open balusters, to maintain a sense of openness and lightness.

Outside Deck Balusters

Outside balusters, or on-top-of-the-joist installation, involve attaching the balusters to the top surface of the deck frame. This method is simpler and faster than installing balusters on the inside, making it a popular choice for DIY enthusiasts.

One of the main advantages of outside balusters is the ease of installation. Since you're working from the top of the deck, you can quickly and easily secure the balusters without needing to measure and cut them to fit between joists.

Installation Process

To install outside balusters, simply measure and mark the spacing along the top of the deck frame. Then, attach the balusters using screws or nails, driving them through the baluster into the joist. Ensure you use appropriate fasteners and follow the manufacturer's guidelines for the best results.

It's crucial to maintain consistent spacing between balusters to meet safety standards and maintain a uniform appearance. Typically, balusters should be no more than 4 inches apart to prevent small children or pets from passing through.

Design Considerations

Outside balusters can create a classic, traditional look, especially when combined with decorative handrails and newel posts. They work well with various baluster materials, including wood, metal, and composite.

However, it's essential to consider the visibility of the balusters from below. If your deck is elevated, you might want to choose a design that allows for some visibility, such as glass or open balusters, to maintain a sense of openness and lightness.

In the end, the choice between inside and outside deck balusters depends on your personal preferences, the specific design of your deck, and local building codes. Both methods have their advantages and can contribute to the overall appearance and safety of your deck. Always prioritize safety and consult local regulations when making your decision. Happy building!
